Portugal captain Cristiano Ronaldo said his ¡°work is done¡± in Europe, adding that he is relishing new challenges both on and off the pitch after being unveiled as a player of Saudi Arabian club Al Nassr on Tuesday.

Ronaldo, who was a free agent following his acrimonious split with Manchester United in November, joined Al Nassr last week on a 2? year deal estimated by media to be worth more than €200 million ($211 million).

He was greeted by a sea of yellow and blue at Al Nassr¡¯s home ground Mrsool Park, where thousands of fans turned up to witness his unveiling.
